FUEL-BUBNING FURNACE.

Application filed December F ennvide a furnace lining and means for sus-' pending the same and introducing there through into the furnace air, or vapors, or pulverized fuel or dust mingled with the air, gas or vapors, to assist in maintaining combustion in said furnace and cooling the suspension members.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which,

Fig. 1 shows in perspective a portion of a furnace lining embodying my invention with a portion of the lining shown in section;

Fig. 2 shows in detail a modified form of a portion of the side wall and support;

Fig. 3 shows another modification of a portion of the side wall and support;

Fig. a shows a plan View of one of the reins of Fig. 1;

Fig. 5 shows a vertical section of the same;

Fig. 6 is a sectional view of one of the side blocks of the lining of Fig. 1;

Fig. 7 shows in vertical section one of the side horns of the structure shown in Fig. 1; and

Fig. 8 shows in vertical section the horn of Fig. 2.

Referring more particularly to the drawings, 1 and 2 are counterpart blocks of refractory material forming a portion of the roof of a furnace lining. 3 is one of the side blocks, while 4 and 5 are lower side blocks used in making the upright wall of the lining. The blocks 1 and 2 are provided with laterally extending recesses 2 as shown in the portion in section at the right of Fig. 1, said recesses being connected with the interior of the furnace by a channel 6 formed by opposing grooves formed in the blocks 1, 2. Between the blocks 1, 2 are T-shaped horns 7, each having a duct 8 discharging through ports 9, 9 in the lateral extensions 31, 1919. Serial No. 348,547.

of the horns 7 and also through an axially arranged port 10. This horn 7 is provided with an internally screwthreaded nipple 1 into which screws a Vertical branch conduit there being one branch conduit for each horn. These branch conduits are connected to main conduits 13, being secured therein by nuts 14: within the main conduits and into which the branch conduits 12 are screwed. The port 10 is in alinement with the axis of the corresponding branch conduit. The horns 7 support the blocks with which they engage and in turn are supported by the branch conduits 12, which in turn are supported by the main conduits 13, the branch conduits being connected to the main conduit in multiple. By this means the blocks of the roof are supported and air, gas or vapor with or without dust can be forced into the recesses through the conduits 12 and the horns 7 and thence through the channels 6 into the interior of the furnace, acting to assistin maintaining combustion within the furnace and also to cool the suspending means.

The blocks 3 and 5 composing the side walls of the furnace are provided with recesses 2 corresponding to the recesses in the blocks 1 and 2 and are supported in a somewhatsimilar manner, but the side block 5 is provided with a perforation which passes through the body of the block and dis charges into the interior of the furnace and is shown at 6. Supporting the next tier of blocks 3, I use a horn 15 having a single extension 16, provided with a duct 17, as shown in Fig. 7. Inthis case the conduit 18 supporting the lower horn 7 is divided at the horn 15, the two ends being screwed into the lower and upper tapped holes of that horn 15 so as to be spaced away from one another and afford a communication with the duct 17. The upper lengths of the conduits 18 supporting the side walls are connected in multiple to a main conduit 13, through which air, gas, Vapor, etc, can'be discharged into the interior of the furnace through the ports 6.

In the modification shown in Fig. 2, the horn 15 supporting the upper side wall block is inserted in an opening in a continuous conduit 18. In the modification shown in Fig. 3 the horn is in the form of the end of a pipe 19, which passes through a supporting Wall 20 into a recess in the block 3 and discharges through a passage 2 into the interior of the furnace the pipe 19 and Wall 20- co-operating to support the block.

By the means describe 1 the blocks forming the linin are securely supported and the supporting means are subjected to a cooling medium discharging into the furnace which may or may not carry pulverized fuel.

As Will be evident to those skilled in the art, my inventionpermits of various modifications Without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a furnace lining, the combination of plurality of blocks arranged side by side having laterally extending recesses in their adjacent faces connected Withthe interior of said furnace, horns having portions extending laterally into said recesses and sup.

porting saidbloclrs, and means for supplying air to said recesses and thence discharging it into the interiorof the furnace.

2. In a furnace lining, the combination of a. plurality of blocks having laterally extendingrecesses therein connected to the furnace interior, horns having portions on opposite sides thereof extending laterally into said recesses and supporting said blocks, and conduitsconnected to said horns, said conduits discharging through said lining into said furnace and supporting said blocks through said horns. 1

3. In a furnace lining, the combination of aplurality of blocks having laterally extending recesses therein connected to the furnace interior, horns extending laterally into said recesses andsupportingsaid blocks, said horns having ducts, and vertically arranged-conduits connected to said horns and discharging through said ducts and thence into the furnace, the vertically arranged conduits supporting said blocks through said horns.

4. 111 a furnace lining, thecoinbination of a .plurality of blocks having laterally extending recesses-therein connected to the furnace interior, horns extending laterally into said recesses and supporting said blocks, said horns having ducts, and conduitsfleading from the outside of said lining and connected to said horns and discharging through aid ducts and thence into the furnace, the conduits supporting said blocks throughsaid horns, said ducts terminating in laterally extending portions of said horns and discharging into said lateral recesses.

5. In a furnace lining, the combination of a plurality of blocks having laterally extending recesses therein, conduits -extending into said blocks from the outside of said lining, T-shaped heads on said conduits supported thereby and supporting said blocks, said heads having ducts connected to said conduits anddischarging through said lining into the interior of said furnace.

6. In a furnace lining, the coinbinatio of a plurality of blocks having laterally en tending recesses therein, conduits extending into said blocks fI'OlililiG outside of said lining, T-shaped heads on said conduits supported thereby andsupporting said bl she, said heads having ducts connected to said conduits and discharging through said lining into the interior of said furnace, said ducts having three openings in each head, one at each end of each lateral extension of each head and one in line with the axis of said conduit. 7 V

7.- In a furnace lining, the coinli ination of a plurality of blocks having laterally extending recesses therein connected to the furnace interior, horns extending laterally into said recesses and supporting said blocks, ducts in said horns, branch conduits leading from the outside of said lining and connected to said horns, said branch conduits discharging through said horns and thence into said furnace, and a main conduit to Which said branch conduits are connected in multiple, said main conduit supporting said blocks through said branchzconduits and horns.

8. A furnace lining, having, in combination, a plurality of blocks constituting the roof of the lining having a plurality of air passages leading from the interior thereof into the'fire boX'of the furnace, and hollow upright hangers extending into said air passages for supporting said blocks and for supplying air to saidipassages.

9. A furnacelining having, in combination, a plurality of blocks arranged side'by side constitutingthe roof of the lining having alrpassages formed ad acent faces there-' of leading into the/fire box of the furnace, and members extending between the blocks and having lateral projections extending into said passages for supplying airto'said passages and for supporting the blocks.
